Daytime Running Lamps (DRL)

WARNING: This page is about a different car, the 2003 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.

The daytime running lamps (DRL) system consists of the following:

Daytime running lamps (DRL) control module
- Resistor
- Relay

The daytime running lamps control module operates the low beam headlamps at a reduced voltage when the ignition switch is in the ON position, the parking brake is disengaged, and the headlamp switch is OFF. Although the DRL system uses the low beam filament of the headlamp, it has a voltage-reducing resistor to dim the headlamps for daytime operation. This allows the flash-to-pass function during DRL system operation.

The DRL module is located under the instrument panel on the driver-side.

The DRL resistor is a part of the DRL module. For removal and installation, refer to DAYTIME RUNNING LAMPS (DRL) MODULE .

The DRL relay is mounted under the DRL module and is available separately.
